//! defines a Group node of VRML specifying group properties.

//! the child nodes and does not alter the traversal state in any way.
//! During traversal, state accumulated for a child is passed on to each successive
//! child and then to the parents of the group (Group does not push or pop traversal
//! state as separator does).
